WASHINGTON (AP) -- A study says that new digital files of historical recordings are at risk of being lost much faster than older ones on tape.
The study also says many historical recordings already have been lost. It says that even newer recordings such as those about 9/11 or the 2008 election are in danger of being corrupted.
Study co-author Sam Brylawski says digital sound files must be constantly maintained and backed up as technology changes. He says that requires active preservation, rather than simply placing them on a shelf.
The first comprehensive study of the preservation of sound is being released Wednesday by the Library of Congress.
Researchers say many sounds are already lost, including most of radio's first decade. That includes shows by singers Duke Ellington and Bing Crosby.
